The watch dial has two clocks. It can display the time on both clocks simultaneously. As far as I understand, either the time of two different countries can be set and tracked at the same time, or the time the plane has been in the air can be tracked on this watch display. The watch is in working order. The buttons are active. Pressing the red button in the lower right corner can reset the small clock to 12:00, like a chronometer. When the button in the bottom left is pulled up, it switches between two hourly setting positions, and it stops working every two clocks to conserve power reserve. The watch has a mineral glass. The button corresponding to the number (6) can deactivate the second small clock dial. The white-red colored function there indicates the active/passive status of the second small clock. The second small clock is white and passive (can be set to non-functional). It is a beautiful collector's item. It must be 8 days rezerve clock , because ı do half opwinding the main spring and it still working during a few-during days. It was acquired from an artist in 1997-1998. The pivot was repaired. No other work has been done on it. The watch case and buttons are in their original paint. NOTE: I do not accept sales via escrow account. I can sell the watch after the price of the watch is received in my personal bank account.
